It's a mildly customized SR1911 lightweight commander from either 2016 or 2017 that I picked up via trade recently. The stainless slide was cerakoted by a local shop in a blue/black/gray color. The mainspring housing is a chainlink pattern, trigger is serrated, the rear sight is a 10-8 and the front sight is a Trijicon. In the box were the original parts, Ruger grips, and grey/blue/green VZ grips.
I gave up a Kahr PM-9 for it.
